To which ring?
If you have a payment ring, I believe the ring itself is linked to an account by a financial institution.
In Australia, Mastercard briefly had an NFC tag that we could get and then link to an existing account via a serial number.
Perhaps the new breed of Visa rings will work in a similar fashion. We'll have to wait and see.

Yeah, @Omer , I'd hazard an educated guess that Australia will be perfectly set up for using an NFC payment ring, what with the way we've taken to paywave and paypass terminals. I'm not sure how you mean though, with "configure"? Most of the behind-the-scenes stuff will be down to the banks and transaction providers.

If you click the "pre-order" button on nfcring.com at the moment it will ask for your email to add you to the mailing list. As soon as there's an update on availability or usage then you should get an email.

As far as I'm aware it should be fine to work on the contactless readers in Australia, they're everywhere and they are proven to work with small tags (I've tried it myself with bank-issued ones).

Until there is more info directly from the NFC Ring guys we won't know whether it'll be pre-paid or added to your current account or whatever, we'll have to wait and see. By all means add your name to the mailing list!

I'll second that. @johnyma22 can you share anything with us about the format of the ring-as-card - will it be linked to existing account, a prepaid card that we can pre-load with funds, or some combination of these?
